We spent the morning wandering through the Marais District, peaking into beautiful courtyards, walking through the Jewish quarter and enjoying a picnic at the Place des Vosges.  After some free time, we met in the early evening at the Louvre.  One cannot imagine the sheer size of the Louvre unless you've been there, and even then it is hard to believe. Covering over 652,000 square feet with more than 35,000 pieces displayed at one time, it is completely overwhelming. Luckily we had our own, wonderful, personal tour guide that made sure we saw the "must see" highlights  and helped us decide where we might want to spend any extra time. The Mona Lisa: of course it is a must see, but it was much more entertaining to watch all of the people crowd around this quite small painting and the guards chiding people for taking flash pictures. You get a bit of a feeling of what some of the stars are dealing with when they are surrounded by papparazzi!
